To all who m, it may concern.

Be it known that I. SAMI'J'EIJ TOY, a subject of theRussian Government, and resident oi? Boston, in the county of Suffolk 5 and State of Massachusetts, have invented a new and useful and improved Finger- Measuring Device, of which the following is a specification, reference being had to the accompanying sheet of drawing, forming part thereof.

My invention relates to a finger measuring. device, and has for its object to provide a simple and reliable means for in- .dicating the size ofiring required to fit the l5 fingerbeing measured in the device.

. ,Another object ofthe invention is tor provide acompact and handy measuring device designed to accommodatethe insertion of a finger therein to berneasuredhthereby,

released by the operatorafter noting the indicated reading of the device.

Other objects and advantages of the in:

30 vention will be gathered from the descrip- .view' of the, device.

Like reference characters refer to like parts throughout-the several viewsofthe 70 and provided ithyieldable means which adapted to automatically expand back to. the normal position immediately upon. being tion following herein and considered in con-. nection with the. accompany ng, drawing,

whereinithe invention is shown embodied.

The terms employed herein are used n the .35 generic. and descriptivesense todesignate the elements lllustrated, and are therefore not primarily intended as terms of limitation.

In order to illustrate my invention I have 40 shown an embodiment thereof in the accompanyingdrawing wherein: p p a Fig. 1. represents an enlarged elevational.

thereto in any suitable manner for permitting the engagement of a chain or cord therewith. M represents the yield-able and overlapped band or measuring element of the devlce which IS IDZILlG oi suitable yieldable material, as springsteel for example, to

afford the measuring element necessary yielding quality to contract and expand within tl e easing ring Q, as.thedrawing in- .dicates and as may be understood to be required by the operating p1l11Clpl6S Of tl1Q device. Said measuring element is normally expanded to fit substantially W concentric within the interior of the casingring C, as shown in Fig. 1., and is securely anchored 5 at an intermediate point A. thereof to the ring casing, as by being riveted, thereto, as

shown... or othelwvise according as maybe desired. The ends Mg and hi of said measuring element, M are preferably over.- lapped as shown in Fig. 1, the l11 111; f0llower end M being provided wit-luthe indicator loop I which slidablv embraces the measuring element; and the; registering m C, 9.5,.l11d1021l3t3d in.

the .measur ing elementM is provided with illig. l, repres ents a left end view of the a d ZfihQWl Q th thehand trigger'T which is exposed through G to perm t. e-;eng agemen .therfl f hand H of the operator, as shown in Figs. 1 and 2 for manipulating the device thereby, as may be understood therefrom. Said indicator loop I and said trigger T may be made integral with the measuring element M, as shown, or separate therefrom and rigidly secured thereto in any suitable man-- ner and according as may be desired.

From the aforesaid description of the parts 01" the device in detail, it will be understood that the device normally assumes the full open and expanded position shown in Fig. 1.- To measure the size of ring required for a particular finger, as F for example, the latter is inserted through the de vice, as. shown in Fig. 3, while the measuring element is allowed to remain in its normal and full open setting. The operator then moves the trigger T around the slot S in the direction of the feathered arrows indicated in Figs. 1, 2 and 5, which operation contracts the yieldable measuring element M, causing the indicator loop I to simultaneously move with the trigger T but in the opposite direction and along the graduated scale G provided on the casing ring C. The overlapped setting of the measuring element ends, namely, M and M, which are each slidably anchored to the casing ring C, provides a cam action therebetween, that is to say, the embracing or leader element M serves as a cam against the other indicator loop or follower end M of the yieldable measuring element M and serves to compel the latter end to function correspondingly in accordance with the setting of the triggerT. The latter is thus moved in the slot suiiiciently to contract the measuring element so that the same becomes wrapped around the finger F being measured, as shown in Fig. 3, when the advancing indicator loop I will show the size of ring required on the graduated scale G, as shown in Fig. a The operator noting the reading may then release the finger F from the device by permitting the trigger T to return to its normal position, which it will do because of the normal expansion and spring feature embodied in the measuring element.

It will thus be noted that the within finger measuring device atlords a simple and reliable gauge for jewelers, which may be carried on a lrey ring or chain to be accessible, and by means of which they may readily and conveniently determine the size of ring required to lit the finger of the purchaser.

Having thus described my invention in detail, what I claim as new is:

1. A finger measuring device, comprising); a ring member having a normally expanded and overlapped band element positioned within said ring member and anchored at an intermediate point thereotto said ring member, said band element normally setting adjacently against said ring member and having the ends thereoi' provided with ring engaging members which slidably engage said ring member; means For crmlraciiu; said band element to encircle the finger being measured in the device; said device hcing provided with means for indicating the degree of contraction of said band element.

2. A finger measuring device, comprising: a fixed frame member having a graduated ring scale provided thcrconr and a yieldaole band member i-iccured within said frame member and adapted to contract and c);- paud diametrically thcrciu, having; the middle portion thcrcof anchored to said l'ramo member and the ends thereof overlapped to yield a leading end and a following cud, whicl following end is controlled by thc aw tions oi the leading end, the latter cud having hand engaging; means slidabl engaging with the frame member for manipulating purpo. and the follower end having indicator means slidably embracing said leading); end of said yieldable band member and said frame member for registering with the graduated ring scale provided thereon to indicate the size of ring required to come spond to the particular setting of said yieldable band member.

3. A finger measuring device for gauging: ring sizes, comprising a rigid outer ring member having a graduated ring scale thereon, and a yieldable inner band member secured. at an intermediate point thereof to said outer ring member and having a leader and follower end adjacently ovcrlapped and adapted to slidably engage with said outer ring, said yieldablc inner band normally spreading against said outer member; a trigger member provided on the leader end of said inner band and projecting beyond the outer hand for manipulatlingthe inner baud therein; and imlicator means provided on the Follower end of said inner band, adapted to slidably cmbracc the leader end of said inner band and said outer ring for registering with the graduated scale provided on the latter.

4. A finger measuring device, comprising a circular shaped rigid outer member, havinga graduated scale of ring sizes provided on one side thereof and a slotted aperture on the opposite side thereof; and a yieldablc circular shaped band member fitted within said outer member, having; the ends thereof overlapped. the outer end serving as the leading end which is provided with a leader trin er slidably engaging the slotted ape)- ture oi. said outer member and the inner end serving as the following end which is provided with an indicator loop which slid ably embraces the leading end of said yieldable band member and said outer member and is adapted to register with the scale provided on the latter, said yieldable band member being anchored at an intermediate point to said outer member and normally adapted to expand to adjacently fit said outer member and otherwise to contract diametrically in accordance with the position of the leader trigger in said outer member.

5. A finger measuring device, comprising a rigid frame member having a graduated ring scale provided thereon on one side thereof and a slotted aperture 011 the other side thereof; and a yieldable circular shaped and expanded band member, having the ends thereof overlapped to provide a leader end and a follower end and the intermediate portion thereof anchored to said rigid frame member, said leader end having a trigger slidably fitted Within said slotted aperture of said frame member and said follower end having an indicator member slidably embracing said leader end of said yieldable band member and said frame member and adapted to ride along the graduated scale section of said frame member for indicating the size of ring required by the particular setting of said yieldable band as efiected by the manipulation of said trigger in the aperture of said frame member.
